Kryptops:

This abelisaur was one of the earliest and most primitive of its kind. It lived about 110 million years ago in Niger, Africa. It was only half as big as the later abelisaurus . Its face was covered with a bony coating . One of the fossils has an intact upper jawbone and the waiting replacement teeth can be seen inside the bone. This dinosaur lived at the same time as Spinosaurus , Nigersaurus , Ouranosaurus and Ludusaurus
